Tangri 2011 4-variable Kidney Failure Risk Equation: 2- and 5-year risk of dialysis or transplant from age, male, eGFR, and urine ACR (mg/g). Risk = 1 - S0^exp(LP) with that paper's 4-variable coefficients. Caller supplies eGFR; magent does not compute CKD-EPI or assay ACR. Not the 8-variable model, not Tangri 2016 country S0, no race. Not a dialysis or transplant order. Not a medical device.
